使用ABAQUS有限元软件对高体分SiCp/Al复合材料的颗粒和基体进行分别定义，仿真研究了高速切削复合材料时的温度场，分析了切削过程中切削用量和刀具角度对工件切削温度的影响。结果表明：在切削过程中，与刀具接触位置的颗粒温度较高且应力值较高；SiC颗粒的温度较Al基体的温度低；第一变形区发现一条沿着剪切角方向非常明显的温升带。在稳定切削阶段，与刀尖接触位置的工件温度较高，且应力集中现象总是发生在SiC颗粒上。随着切削深度和切削深度的增加，切削过程中工件的最高温度均随之增加；随着刀具前角和后角的增大，切削过程中工件的最高温度均随之降低。

In this passage,the finite element software ABAQUS was used to define both the particles and matrix dur-ing high speed cutting SiCp/Al composites.The temperature field of high speed cutting SiCp/Al Composites was studied in details and the influence of cutting parameters and cutting tool angle on the cutting temperature was analyzed.The results indicated that the temperature and stress of particle which contacted with the cutter were higher.The temperature of the Al matrix phase was higher than the SiC particle and in the primary deformation zone there was very obvious temperature zone along with shear angle.In the stable cutting stage,the temperature of the position which was contacted with the tip of cut-ting tool was higher and the stress concentration phenomenon was always happened on the SiC particles.With the increas-ing of cutting speed and cutting depth,the high temperature in the cutting process was increased.With the increasing of rake angle and relief angle the high temperature in the cutting process was decreased.
